SPECIFICATION forming part of Letters Patent No.44'7,862, dated March10, 1891.

ApplicationfileclNovember20,188$. Renewed December 10, 1889. Serial No.333,179. (Nomocleld To all whom, it may concern.-

Be it known that I, THEODOR BERGMANN, a resident of Gaggenau, in Baden,Germany, have invented an Improved Vending Apparatus, of which thefollowing is a specification.

The object of my invention isto provide improvements in coin chutcs forvending apparatuses; also, to provide improvements in coin conveyers andsupports for such apparatuses, and improved means for closing thecoin-chute to prevent the entry of coins after the packages have beenremoved from the apparatus.

The invention consists in the details of improvement and thecombinations of parts that will be more fully hereinafter set forth",and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is an elevation of a vendingapparatus, theback of theapparatus being removed, disclosing myimprovements. Fig. 2 is a vertical cross-section on the line 7.: k,Fig. 1. Fig. 3 is an enlarged detail sectional viewon the plane of theline 0 c, Fig. 6,showing the coin conveyers and supports and a portionof the coinchute. Fig. 4 is a vertical cross-section on the line 0 c,Fig. 1. Fig. 5 is an enlarged detail plan view on the plane of the linek Fig. 3, showing my improved coin conveyer and support in the rearwardor coin-receiving position; and Fig. 6 is a similar detail View showingthe coin conveyer and support in the forward or coin-expelling position.

In the accompanying drawings, the letter A represents the casing of avending apparatus,which may be of approved construction.

In the drawings, the casing A is provided, as shown in'Fig. 1, with twocompartments B, in which may be placed packages D, one upon the other,as shown.

Between the two compartments B, I prefer to place two coin-chutes E,that extend from the front of the casing A about to its back, as clearlyshown in Fig. 2. These coin-chutes E at the front of the casing comeopposite openings a, therein, through which the coins may be passed tosaid chute. The chutes E are cut away for a portion of their length, as

at b, (see Fig. l,) thereby leaving ledges Z) at the sides, upon whichthe edges of a coin may rest. These ledges are at such a dis tance apartthat a coin'of proper size will rest upon them and pass down the chute;but a coin of less diameter will fall through said chute to a receptacleF. On the outside of the casing A, I prefer to secure a slotted blockd,whose slot is aligned with the opening a. The slot in the block d shouldbe'of such a size as to permit the en try of'a coin of proper size, butto prevent the entry of a coin'of larger size. Thelower ends of thechutes E lead to the upper ends of chutes G,'so that coins may pass froma chute E to a chute G. (See Fig. 2.) The chutes G 'aresituated back ofthe compartments B, theiulowerjends coming about in line with the bottomof the compartments B. The chutes G consist of two plates 6 f, that areconnected together at their edges for a short space near their lowerends by an intermediate strip or the like, but are not con' nected attheir edges above that part whereby a chute having an open upper andlower part is formed. The bottoms of the chutes G are also open for theexit of coins, one side of said chute at the lower end being preferablycut away, as at 9 for the passage of a coin.

H is a lever that is pivoted atabout its center, preferably about inline with the center of the chutes E when two such chutes are used. Theouter ends of the lever H pass through the under openings in the lengthof the chutes G and extend across said chutes, as shown in Fig. 1. Thelever H is to be so balanced that when a coin of proper weight passesinto the chute G it will depress said lever until its lower end comesagainst a stop g in the chute. The lever thus depressed fills the underopening in the length of the chute, thereby forming a tread for the cointo run upon to find its exit at the lower end of said chute. The lever Hshould be so balanced that if a coin of less Weight than the proper cointo be used is passed into said chute said lever will not be depressed,but the coin will run along the upper edge of said lever and pass outthrough the upper opening oft-he chute G, as shown in dotted lines attheleft in Fig. 1. The lever H may be Otherwise pivoted and balanced, ifdesired. It desired,the lever H may be replaced by a spring that willact in the same manner.

I are springs that pass along the outer side 5 of the chutes G. Thesesprings extend slightly below the lower ends of the chutes G, and eachcarries a pin it, that passes through an opening '6 in the outer sidesof the chutes G, so as to come in line with and stop the passage of acoin through said chute for the purpose hereinafter set forth. The lowerends of the compartments B are cut away, thereby leaving ledges orguides U at the sides, upon which the packages may rest and I 5 alongwhich they are pushed when being eX- pelled from the apparatus.

, Below the compartments B are my improved coin conveyers and supports J,that are adapted to receive coins from the chutes G. The coin conveyerand support J is constructedas follows: j is a bar that is guided at oneend in a plate Z, the other end of which is connected to a sleeve m,which sleeve surrounds a rod n, that is suitably supported in thecasing. A spring 0, that surrounds the sleeve on, presses at one endagainst a shoulder on said sleeve, and at the other end against a stopwithin the casin g, and thereby tends to move the coin conveyer andsupport backward under the coin-chute G. By means of a ring orotherhandle that projects through the casing from the sleeve m, the coinconveyer and support may be-drawn forward. From one side of the bar j ofthe coin con- 3 5 veyer and support J project lugs 19, that are in theform of hooks that face each other, as shown in Figs. 5 and 6, therebyleaving a recess into which a coin may pass. In the outer ends of thelugs 19 are set-screws q, that are adapted to. project from said lugsinto the recess formed by said lugs. In the bar j of the coin conveyerand support is placed a set-screw 1', that is about in line with one ofthe set-screws q, and that is adapted to pass 5 through the bar j andinto the recess formed by the lugs 19. On the same side of the bar jwith the set-screw 1" in lug 3, carried by the bar j, is pivoted a leverL. One'end of the lever L is pressed toward the bar 9' bya helical 5ospring 15, that is preferably situated at the opposite end of saidlever. to isa set-screw that is carried by thelever L, and that passesfreely through the bar j of the coin conveyer and support J, as clearlyshown in Figs. 5 and 6. This set-screw u is adapted to pass into therecess formed by the lugs 19.

To support a coin of proper size in my improved coin conveyer andsupport, the setscrews q q, r, and u are adjusted so that the edges of acoin will rest upon and between the ends of said setscrews. Thisadjustment may be made very delicate, so that when the lever L is turnedon its pivot to move the setscrew toaway from contact with the coin Msaid coin will lose its support and will drop from the coin-conveyer.

In order to move the lover L on its pivot at outward,'as clearly shown'in Fig. 6.

the proper moment, I secure in the path of the coin conveyer and supportJ arod N, that is preferably adapted to pass through one of the lugs andthrough the barj, and to come in contact with the lever L to move theend of the lever carrying the set-screw a slightly This rod N issituated over a chute O, that is adapted to receive the coins from theconveyer and support, when said coin has acted to push a package fromthe compartment B above said conveyer.

P is a lever that is pivoted below the coin conveyer and support J, sothat its upper end comes in line with the lower edge of a coin whencarried by said conveyer, said lever being adapted to prevent the returnof the conveyer after the conveyer has passed said lever and while thecoin is retained in said conveyer. A more full description of this leverwill be found in Letters Patent No. 413,009, Adriance, dated October 15,1889.

R is a weight that I place in the compartment B upon the pile ofpackages D. To the weight It is attached a chain or other connection (R,the upper end of which is connected to a rod b This rod 6 I prefertomake with the horizontal port-ion, to which saidchain is secured andwith a vertical portion, the lower end of which is adapted to come inline with the opening aim the casing. By means of a spring (1 the rod 17is elevated when the weight B does not draw upon the connection a IVhenthe weight R-is'placed upon the packages D, the spring (1 will raise therod 19 moving it out of line with the opening a. When the last packagehas been removed from the compartment B, the Weight R, by drawing uponthe connection aa'will draw down the rod b thereby moving its end overthe opening 00 by this means preventing the entry of any more coinsuntil the weight R has been elevated by placing packages beneath it. Bythe above construction I produce an automatic closing of thecoin-opening when the last package has been delivered.

My improvementsv operate as follows: Supposing the compartment B to beprovided with packages and the weight R placed upon said packages, therod b thereby being moved out of line with the opening a and the coinconveyer and support J to have been moved by the spring 0 back beneaththe coin-chute G inposition to receive a coin. The coin is now placedinthe apparatus when it passes along the chute E, thence to the chute G,and depresses the lever H, which forms atread for the coin. The cointhen passes from the chute G into the coin conveyer and support J, andrests upon the ends of the set-screws q q, r, and u. The purchaser nowdraws upon the sleeve on, which moves the coin-conveyer forward, therebybringing the coin M in contact with the lowest package D of the pile ofpackages, thereby pushing said package forward alongits guides Z P, sothatit will drop over the edge T, and through the openingat the end ofsaid guides, and fall down in front of the apparatus, as shown in Fig.4. As the coin conveyer and support J is moved forward and reaches therod N, said rod will pass through said conveyer, and at about the momentthat the package has been pushed as far as the coin can push it the rodN will strike the lever L, thereby moving said lever, and with it thescrew u,from contact with the coin,thus releasing the coin, when thecoin will drop from the coin conveyer and support J into the chute O,the package meanwhile dropping from the coin conveyer and support J. Thespring 0 will return the conveyer and support J to its position beneaththe coin-chute for receiving another coin when the operator releases thering or handle. WVhen the conveyer and support is in the coin-receivingposition, it will engage the end of the spring I and move said springoutward so as to draw the pin it outward to give a free passage throughthe chute G for a coin. hen the coin conveyer and support is movedforward, the spring I will also move forward, so as to bring the pin hacross the chute G. If now a person should place a coin into theapparatus when the coin conveyer and support is not beneath the chute G,the pin h will prevent the passage of the coin from the chute G. On thereturn of the taining two compartments for packages, two

sets of coin-chutes, and two coin-conveyers, it is evident that theapparatus may be constructed with only one such set of devices or withany number desired. It is also evident that the relative arrangement ofparts may be varied to suit the requirements of diflferent apparatuses.

Having now described my invention, what I claim is- 1. The inclinedchute G, open on its upper and lower sides, combined with the pivotedbalanced lever H beneath said chute, the end of said lever passing intosaid chute from the under side, said lever forming the bottom of thechute and being adapted to be depressed by a coin of proper weight toform a tread for the coin, and to cause a coin of less weight to passout of the upper side of the chute, sub stantially as described.

2. The inclined plates e f, connected together on their edges near oneend and free on their edges above said connected part, thereby formingopen upper and lower sides, combined with the balanced lever II belowsaid plates, the end of said lever being passed between said plates fromthe under side, thereby forming a tread for a coin of proper weight, andcausing a coin of less weight to pass through the upper side of thechute, substantially as described.

3. The chute E, having an opening I) and edges 1) at the sides of saidopening, combined with the inclined chute G, having open upper and lowersides, and with the balanced lever H below said chute, the end of saidlever being passed within said chute from below, and with a stop g forthe end of the lever, said lever thereby forming a tread for a coin,substantially as described.

4. In a vending apparatus, the combination, with the casing having anopening a for the entry of coins, of a rod 1) for passing across saidopening, a spring for raising said rod, and a weight for depressing saidrod, substantially as described.

5. The combination, with a chute having an opening 2', of a spring I,having a pin h for passing into said opening, and with a pusher thatengages said spring, and a lever H for passing across said chute, allarranged for operation substantially as herein shown and described.

6. In a vending apparatus, the bar j, carrying screws q q and 7",combined with the movable screw u, said screws being adapted to supporta coin in the conveyer and to release said coin when the screw it ismoved, substantially as described.

7. In a vending apparatus, the bar j, carrying screws q and '1",combined with the movable screw it and with the rod N for moving saidscrew, all arranged for operation substantially as herein shown anddescribed.

8. In a vending apparatus, the bar j, carrying screws q and 1", combinedwith the lever L and screw to, that is carried by said lever, and withthe rod N for moving said lever L and screw u, substantially asdescribed.
